            Bug ID: 300179
          Severity: crash
           Version: 0.3
          Priority: NOR
          Assignee: kde-telepathy-bugs at kde.org
           Summary: Right click in status line followed by click anywhere
                    else leads to segfault
    Classification: Unclassified
                OS: Linux
          Reporter: devurandom at gmx.net
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: contactlist
           Product: telepathy

Application: ktp-contactlist (0.3)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I right clicked in the status line of the contact list (where the mouse cursor
takes text cursor shape) and then clicked somewhere else (inside the window, or
outside - makes no difference).

The crash can be reproduced every time.

-- Backtrace:
Application: KDE-Telepathy-Kontaktliste (ktp-contactlist), signal: Segmentation
